The perimeter is the sum of all of the lengths of the sides. To find the perimeter, add together the length of each side.
For this triangle, our side lengths are 7, 7, and 9.
7 + 7 = 14
14 + 9 = 23
The perimeter of a triangle that has two sides measuring 7 centimeters and a third side measuring 9 centimeters is 23 centimeters.
Hope this helps!! :)
The pool must have been the same depth at the start of the interval as it was at the end of the interval.
The pool must have been deeper at the end of the interval than it was at the start of the interval.
The pool must have been more shallow at the end of the interval than it was at the start of the interval.
Answer: The pool must have been the same depth at the start of the interval as it was at the end of the interval.
Explanation:
The average rate of change is calculated as:
[final value - initial value] / time interval.
Then, the average rate of change does not take into account intermediates values, and you cannot draw any conclusion about such intermediate values.
In the given case you have:
average rate of change in depth = [final depth - initial depth] / 2 weeks.
0 = [final depth - initial depth] / 2 weeks.
⇒ 0 = final depth - initial depth
⇒ final depth = initial depth.
That is why the conclusion is the second statement of the answer choices: the pool must have been the same depth at the start of the interval as it was at the end of the interval.
In between the pool might have been deeper, more shallow, empty or change in any form, since the average rate of change does not tell the full history but only the net change.
Answer:
the inverse is :10^x/2
Step-by-step explanation:
f(x)= log2x.
f^-1(x)=10^x/2
3x^2y(2x^2y^2 + 7xy − 3)
3x^2y3&(2x^2 + 7xy − 3)
3x^2y(2x^2y + 7xy − 3y)
The simplest factored form of the expression 6x^4y^3 + 21x^3y^2 − 9x^2y is 3x^2y(2x^2y^2 + 7xy - 3), derived by taking the greatest common factor (GCF) out from each term.
The task here is to completely factor the polynomial 6x^4y^3 + 21x^3y^2 − 9x^2y. Initially, you look for the greatest common factor (GCF) in the terms. In this case, the GCF is 3x^2y. So we factor that out from each term:
3x^2y(2x^2y^2 + 7xy - 3)
The factored form of the original expression is therefore 3x^2y(2x^2y^2 + 7xy - 3). This result represents the simplest factored form of the expression.
